Description

[Detailed description of the device]
The present invention relates to a profile clamp having a clamp band and a pre-positioning means, the clamp band having two flank, the pre-positioning means being connected to the clamp band, and the pre-positioning means being at least It has one fixed part.

  Typically, profile clamps are used to connect two tubes that have a connecting flange at their ends. In this case, these profile clamps usually press the connecting flanges towards each other by enclosing both connecting flanges in front opposite directions. For this purpose, the profile clamp usually has a V-shaped profile. When fixing the profile clamp, not only a radial force on the flange, but also an axially directed force that presses the flanges of each tube together is applied.

  However, the known profile clamp setting is relatively difficult in many applications. Especially in a confined space environment, it may be difficult for the mechanic on the one hand to press the connecting flanges together and on the other hand to hold and close the profile clamp. Particularly in the field of vehicle use, it may be possible to access the desired pipe connection position from only one direction.

  Here, Patent Document 1 discloses a spring band clamp having a clamp band and a pre-arrangement means. Such a spring band clamp serves, for example, to set the hose relative to the connecting nozzle. Thus, since the spring band clamp need only apply a radially inward force, the clamp band of the spring band clamp typically has a substantially cylindrical cross-section. In this case, the spring band clamp can be fixed to the hose using the hook-shaped tip by the pre-arrangement means.

  However, such pre-positioning means are inadequate in profile clamping for several reasons. On the one hand, prior to the prepositioning of the profile clamp, the profile clamp is relative to the position of the connection flange so that the second connection flange can be guided on the front side relative to the first connection flange. It is necessary to be held at a distance in the radial direction. This is exactly the opposite when pre-positioning the spring band clamp as described above, as it is desirable to position the spring band clamp as close to the hose as possible and possibly pre-position in mesh. It will be effective. On the other hand, the tip for securing the spring band clamp to the hose can lead to leakage by penetrating the tube, making it inappropriate to apply to the profile clamp.

German Patent Application Publication No. 10 2008 047038A1

  The present invention is based on the problem of providing pre-positioning means for profile clamps in order to facilitate the installation of profile clamps.

  In the present invention, this problem is solved by extending at least one fixed part in the axial direction opposite one flank and radially inward of both flank.

  With prepositioning means having such a fixing part, it is possible to preposition the profile clamp with a sufficiently large radial distance relative to the first tube in the region of the first connecting flange. This also prevents the clamp band of the profile clamp from interfering when the second connecting flange is guided on the front side with respect to the first connecting flange. Therefore, the installation of such a profile clamp is remarkably simplified, and a mechanic can perform it alone without any problem. In particular, it is not necessary to keep the profile clamp open wide enough in the region of the first connecting flange so that the mechanic can guide the second connecting flange.

  Furthermore, it is advantageous for the prepositioning means to have at least one bridge. Such a bridge has, for example, the shape of a sheet metal, passes radially through the clamp band flank from the clamp band in the axial direction and beyond the flank of the clamp band radially inwardly on one tube. Can be a guide. The at least one fixing part can be provided, for example, at the end of the bridge opposite to the clamp band.

  Furthermore, it is preferred that the prepositioning device has at least one substantially flat connecting element. Such an element makes it possible to fix the prepositioning means to the clamp band or tube as easily as possible. The pre-positioning means can be fixedly connected, in particular welded, to the clamping band by means of the first tube and / or another connecting element, for example in the region of this at least one substantially flat connecting element. .

  Furthermore, it is advantageous for the prepositioning means to have at least one carrier band. Such a carrier band makes it possible to obtain a reliable pre-arrangement of the clamp band. Accordingly, such a carrier band can apply a spring force to the clamp band or the end of the tube depending on the arrangement thereof. As a result, for example, it is possible to omit a fixed connection by, for example, a welding process.

  Furthermore, it is advantageous for at least one fixed part to have one carrier band. In such an embodiment, for example, one carrier band can meshly surround the end of the first tube on the opposite side of the first connecting flange. Accordingly, at least one carrier band is arranged opposite one flank and radially inward of both flanks. This makes it possible to ensure that the clamp band is held at a sufficient distance in the radial direction with respect to the first connecting flange.

  Furthermore, it is preferred that at least one carrier band is arranged radially outward with respect to the clamp band. In this embodiment, the clamp band can be held in an open position selected in a particularly good manner. Here, it is conceivable that the pre-arrangement means has not only the carrier band offset in the axial direction with respect to the clamp band but also a carrier band arranged radially outward with respect to the clamp band.

  Furthermore, it is preferable that one bridge is provided at each end on the peripheral side of the at least one carrier band, and these bridges are connected to the clamp band on the radially outer side. In such an embodiment, for example, the pre-positioning means can be manufactured using a single curved sheet metal.

  Furthermore, it is advantageous if the pre-positioning means is fixedly connected, in particular welded, to the clamp band in at least one position. This makes it possible to preposition the prepositioning means in a particularly simple manner in the region of the first coupling flange with the profile clamp.

  Preferably, the profile clamp has two clamping jaws and the prepositioning means are connected to the clamping band at least at two locations in the area of these clamping jaws. In this embodiment, the profile clamp can also be held under preload by prepositioning means. This prevents the profile clamps from opening in an undesired manner radially before final fixation.

  Preferably the pre-positioning means holds the profile clamp under radial preload by spring force. This can be obtained by several means. For example, the pre-positioning means is obtained by being connected to the clamp band by a bridge provided at a distance on at least two peripheral sides. Alternatively, the pre-positioning means can be obtained by having a carrier band provided on the clamp band on the radially outer side.

  Furthermore, it is advantageous that the clamp band has at least two segments and the pre-positioning means are not locked on at least one of these segments. In this embodiment, on the one hand, the prepositioning means can be connected to the clamp band in at least one segment to maintain the position of the clamp band. On the other hand, the profile clamp can be further opened and closed with at least one free segment if required during installation. This is particularly advantageous in closure work, for example, because the free end of the profile clamp must be brought together for this purpose, in order to be able to fix the screw or install the bolt in order to close the profile clamp. Because there is. Here, at least one segment of the clamp band remains free so that it can be bent radially inward, which facilitates closure and at the same time prevents loosening of the preposition. Preferably, the clamp band has four segments and the pre-positioning means only locks against two of these segments.

The invention will now be described on the basis of some preferred embodiments in connection with a plurality of drawings. Illustrated in the drawings is the following:

Example 1
FIG. 1 shows a profile clamp 1 with a clamp band 2 and a prepositioning means 3. The profile clamp 1 surrounds the connecting flanges 4, 5 of the two tubes 6, 7 in the closed state.

  The clamp band 2 has a substantially V-shaped profile including flanks 8, 9, which urge the connecting flanges 4, 5 against each other when the clamp is closed. In the present embodiment, the clamp band 2 has four segments 10, 11, 12, and 13, and the interruption portions 14 and 15 are disposed therebetween. Because of these interruptions 14, 15, the profile clamp 1 has a slightly higher elasticity, so that the individual segments 10, 11, 12, 13 can be bent to open and close the profile clamp without being bent by it. Becomes easy.

  The profile clamp further has a connecting shape 16. Therefore, clamp jaws 17 and 18 are provided at the peripheral end of the clamp band 2. These clamping jaws 17, 18 can be moved towards each other using clamping means 19 to close the profile clamp 1.

  Here, the profile clamp 1 further comprises pre-positioning means 3, which can be used to pre-position the profile clamp at the end of the first tube 6 in the region of the first coupling flange 4. is there. In this embodiment, the pre-arrangement means 3 has a fixed portion 20 that is a component of the bridge 21. Here, the pre-arrangement means is connected to the clamp band 2 from the outside in the radial direction, and at the same time, extends along the outside in the radial direction of the first tube 6. The fixed portion 20 is provided on the radially inner side of the flank 8, 9 of the clamp band 2, and is in this state regardless of whether the profile clamp 1 is open or closed. However, the radial distance between the fixed part 20 and the flank 8, 9 can be reduced by the closing process of the profile clamp 1.

  In the pre-positioning, the pre-positioning means 3 is fixed not only to the profile clamp 1 but also to the tube 6 in at least one fixing part 20 of itself. However, since the prepositioning means 3 is already secured to the profile clamp 1, it may be necessary only to connect the fixing part 20 to the tube 6 for prepositioning. The at least one fixing part 20 is arranged radially inward of the flank 8, 9 of the clamp band 2 so that the connecting flanges 4, 5 can be guided towards each other without problems even after pre-positioning. To the extent, it is established that the flank 8, 9 of the clamp band 2 makes a radial distance to the tubes 6, 7. It is therefore not necessary for the mechanic to hold the profile clamp 1 in position on the first connecting flange 4.

  Here, the prepositioning means 3 has substantially flat connecting elements 22, 23. The connection elements 22, 23 make it possible to easily obtain a secure connection between the pre-positioning means 3 and the clamp band 2 or the first tube 6. The pre-positioning means can thus be welded to the first tube 6 by means of the clamping element 2 and / or the coupling element 23, for example by means of the coupling element 22.

(Example 2)
A second embodiment of the present invention is illustrated in FIGS. Here, the pre-arrangement means 103 has a fixed portion 120 and connecting elements 122 and 123 which are components of the bridge 121 again. Furthermore, the pre-positioning means 103 has a carrier band 124 that surrounds the clamp band 2 from the outside in the radial direction. In this case, the carrier band 124 is disposed in an angular region of approximately 180 degrees on the radially outer side and the peripheral side of the clamp band 2. Thus, the carrier band 124 only locks with the two segments 11, 12 of the profile clamp 110. Thus, the segments 10, 13 can be bent so as to open and close as before, with the pre-positioning being substantially unaffected. Furthermore, the pre-arrangement means 103 may be fixedly connected to the clamp band 2 at the peripheral ends 125 and 126 of the carrier band 124. This ensures that the profile clamp 101 can be pre-positioned, and in particular prevents situations where the profile clamp in the pre-positioned position is unintentionally detached or tilted.

  If a higher stability of the prepositioning means 3, 103 is desired, the prepositioning means can naturally have further fixing parts 20, 120.

(Example 3)
7, 8 and 9, a third embodiment of the present invention is finally illustrated. In this case, the pre-arrangement means 203 has a carrier band 224 that is arranged offset in the axial direction with respect to the clamp band 2. Here again, the carrier band 224 is arranged radially inside the flank of the clamp band 2. Accordingly, the carrier band 224 can be disposed so as to mesh at least partially on the radially outer side of the first tube 6. Here, the carrier band 224 preferably surrounds the first tube 6 by a spring force that surrounds the first tube 6 by 180 degrees or more on the peripheral side and moves radially inward. Here, the fixed portion 220 is substantially formed by the carrier band 224.

  Furthermore, the pre-arrangement means 203 has one bridge 221 at each end on the peripheral side of the carrier band 224. Here, these bridges 221 extend radially outward and in the axial direction toward the clamp band 2. Further, these bridges 221 are connected to the clamp band 2 from the outside in the radial direction, for example. These bridges 221 are preferably locked in the region of the clamp jaws 17, 18 on the radially outer side with respect to the clamp band 2. This makes it possible to additionally realize a pre-closing function by the pre-arrangement means 203. Accordingly, it is possible to prevent the profile clamp 201 at the pre-positioned position from opening to a certain extent unexpectedly. This makes it possible to guide the connecting flanges 4, 5 towards each other without problems on the front side, while at the same time ensuring that the profile clamp 201 is fixedly positioned in a sufficient manner. The pre-positioning means 203 according to the third embodiment has a fixing part 220 surrounding the carrier band 224 so that, for example, a secure connection between the pre-positioning means 203 and the first tube 6 can be omitted. There is an advantage of being. Thus, the profile clamp can be displaced both angularly and axially in the pre-positioned state. Further, in the present embodiment, a secure connection between the pre-positioning means 203 and the clamp band 2 is not essential. Therefore, the pre-positioning means 203 can be removed and reused in some cases even after the clamp is attached.

  Furthermore, by comparing FIG. 7 and FIG. 9, the fixed portion 220 extends radially inward of both flanks 8, 9 whether the profile clamp 201 is still open or closed. It is shown.
